Title: Formation of ultrafine-filament structure
IPC: C07K1/04
Filed: 1991-11-08
Abstract: PURPOSE:To form a biotechnologically designed ultrafine-filament structure, e.g. an ultrafine stereoscopic wiring by bonding an atom or a molecule to a position near the amino terminal end, the carboxyl terminal end, etc., of each structural unit of a procaryote flagellum and polymerizing the resultant modified units. CONSTITUTION:Cultured bacteria are centrifuged in 20mM tris buffer solution (pH7.8) containing 0.15MNaCl so as to collect their flagella. The collected flagella are heat-treated at 65 deg.C for 10min so as to give monomerized flagellins as the constituting unit of the flagellum. An atom (e.g. mercury) or a molecule (e.g. a mercury compound) is then chemically bonded through a covalent bond, a hydrogen bond, etc., to the amino terminal end or the carboxyl terminal end of the protein constituting the D1 region of each flagellin or a position near there and ammonium sulfate is subsequently added thereto so as to polymerize the resultant modified flagellins in a self-assembly-like manner. The flagellum is restructured thereby and the resultant restructured flagella are heated or irradiated with energy rays so as to mutually bond the above atoms or the above molecules. Thus, the objective ultrafine-filament structure is formed.
